When I was there the only gig I managed to drag myself to was at TT the Bear's near Cambridge, which still has some pretty good stuff on from the look of it. And where I got squiffy on Sam Adams; the best kind of squiffy.

When you get there, a pretty good idea might be to head over to Newbury Comics (on Newbury Street; there are others locations, but that was the bestest one) and check out their gig listings (it's more record shop than comic shop).

Other than that, if you hang round the studenty areas (ie. most of it) you WILL find hella fun things to go to. Have fun! I miss it bad.
